Although I'm relatively experienced with Macs and have worked with video in the past, I'm currently a bit stuck on the best overall approach to a project I have at the moment.
I have an audio recording in MP3 format of a talk and corresponding PowerPoint slides. I need to combine these into a YouTube video, so that the PowerPoint slides advance in time with the talk - this will require manual input, as the slides are not timed.
I thought that PowerPoint 2008 (the version of Office that I have at my disposal) had this functionality built in, via the File >> Save as Movie... option, but it doesn't seem to work properly - even if I setup the slide transition timings, the movie file produced is 2 seconds long, goes straight to the final point without any transitions and does not include the selected background audio track.
So I'm looking at other options to get this done.
One option is Camtasia 2 for Mac - in essence using it to capture a screen grab of the PowerPoint deck being advanced in time to the recorded audio. However I anticipate that this will probably produce very, very large video files, as the audio recording is 30 mins long. Camtasia 2 isn't cheap at £80, plus I also had an old version of Camtasia Studio for Windows back around 2003 and it was very, very buggy indeed. So I'm rather hesitant to drop that much cash on another product from the same company.
Does anyone know of a better way to do this, using free, or more affordable good quality software which will produce a reasonable quality end result?
Many thanks,
Andrew
